Summary: The research focused on studying the effects of temperature and pine-to-HDPE ratios on pyrolysis products. Catalytic pyrolysis of HDPE resulted in over 90% selectivity towards gasoline-range hydrocarbons, while pine showed a gasoline selectivity of 69.3%. Addition of HDPE increased gasoline selectivity by improving the hydrogen/carbon effective ratio. Optimal yield and higher gasoline selectivity were achieved at pine to HDPE ratios of 0/100 and 25/75.

Summary: In this study, the impact of mesoporous structure parameters on the diffusion of heavy phenols and the regulation of pyrolysis products in cellulolytic enzyme lignin catalytic conversion was investigated. A micromesostructured composite zeolite (ZMA) with internal hierarchical pores and ununiform mesolayer shell was found to have the most suitable mesostructure for the process, showing improved accessibility of inner acidic sites and providing a balance between aromatic yield and product distribution. Additionally, different mesostructures required varied applicable catalyst to lignin ratios, with ZMA and hierarchical samples suitable for higher and lower ratios, respectively.

Summary: The study investigated the effects of wet torrefaction pre-treatment and Zn/Ni-HZSM-5 on the characteristics of bio-oil produced from the pyrolysis of corn stalk. The synergistic effect between wet torrefaction and the loaded metal catalyst was also analyzed. Wet torrefaction pretreatment reduced the oxygen content of the corn stalk and increased the selectivity of certain compounds in the bio-oil. The addition of the catalyst improved various reactions during pyrolysis and increased the relative content of aromatics.

Summary: This study investigated the pyrolysis behavior of metallized food packaging plastics waste (MFPW) in the presence of a ZSM-5 Zeolite catalyst at different concentrations and heating rates. The addition of catalyst did not have a significant effect on the pyrolysis products, as shown by TGA-DTG results. FTIR analysis revealed the presence of methane and carboxylic acid residues, while GC-MS measurements identified compounds similar to those found in petroleum oil. Additionally, pyrolysis kinetics showed relatively consistent activation energies for catalytic pyrolysis of MFPW samples with different catalyst concentrations.

Summary: Py-GC/MS is a quick and highly effective method to analyse volatiles from small amounts of feeds, combining pyrolysis with GC and MS. This review focuses on using zeolites and other catalysts in the fast co-pyrolysis of various feedstocks to improve specific volatile product yields. Zeolite catalysts, especially HZSM-5, result in a synergistic reduction of oxygen and an increase in hydrocarbon content. The review also discusses the use of metal catalysts, self-catalytic feedstocks, and the combination of catalysts to improve aromatic yield during co-pyrolysis.

Summary: The catalytic conversion of model compounds for plastic pyrolysis oil (1-octene, octadiene, octane, and toluene) over ZSM-5 in a fixed-bed reactor was investigated mechanistically. The conversion of 1-octene resulted in the production of benzene, toluene, xylene, coke, and hydrogen through a series of cracking, oligomerization, cyclization, and hydrogen transfer reactions. Octadiene mainly contributed to reactor fouling through thermal coking, while octane and toluene were converted through cracking reactions and disproportionation, dealkylation, and coking reactions, respectively. The use of mesoporous ZSM-5 maintained product selectivity for 70 hours in time-on-stream experiments.

Summary: A CSMP reactor coupled with an ex-situ catalytic bed was developed for the conversion of LLDPE to high-grade fuels. The addition of HZSM-5 catalyst led to the production of refined chemicals dominated by gasoline-range hydrocarbons. High selectivity of gasoline-range hydrocarbons was achieved at a catalyst-to-reactant ratio of 15% and feeding rate of 6 g/min. The pyrolysis processes yielded ethylene as the main gas product, while propylene and propane were the primary gas components with the addition of HZSM-5. The net energy gain increased with growing feeding rate from 6 g/min to 30 g/min.

Summary: In this study, the concentration and position of sulfur vacancies in ultrathin ZnIn2S4 nanosheets were successfully controlled to optimize the photo-driven lignin model reforming process, leading to excellent selectivity for hydrogen and chemical monomers. The proton migration pathway was modulated through sulfur vacancy engineering, achieving high concentrations of sulfur vacancies in the bulk and on the surface of ZnIn2S4. This provides new mechanistic insights into biomass photoreforming and elucidates the structure/chemistry-catalysis correlation of ZnIn2S4 photocatalysts, which are crucial for photocatalyst design and solar fuel production.

This study examined the impact of volatiles from one feedstock on the biochar of another feedstock during sequential pyrolysis, and found that it reduced oxygen/nitrogen-containing compounds and heavy pi-conjugated components in the bio-oils, increased biochar yields but decreased bio-oil yields, and made the biochars more hydrophobic and thermally stable.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
